Therefore,the Re-Os age of molybdenite in the Lüliang period not only provides evidence for existence of the Pre-Cambrian metallogenic period,but also shows the prospecting direction to find molybdenum deposits and the metamorphic porphyry-type copper-molybdenum ore in this area.
因此,吕梁期辉钼矿Re-Os年龄的获得,一方面证实了前寒武纪成矿期的存在,另一方面也为该地区寻找钼矿及变斑岩型铜钼矿指出了找矿方向。
